COMPOSITION OF MATTER FOR KNIFE-HANDLES.

To all whom it may concern:

Be it known that I HUBERT C. HART, a citizen of the United States,residing at Unionville, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inComposition of Matter for Knife-Handles, of which the following is aspecification.

This invention relates to improvements in a composition of matter,designed primarily for knife handles, but may be used to advantage inother arts.

The object of the invention is to produce a composition of matter whichwill possess strength, and at the same time have sufficient elasticityto prevent of its being easily tle which would make it impracticable forbroken.

Other objects and advantages will be hereout in the claims.

In the drawings I have shown the invenapplied to a knife, Figure 1,being a perspective view. Fig. 2. is a detail view of one section of thehandle.

In the production ofiny improved composition I employ, paper, rags and asolution The rags and paper are ground into-comparatively smallparticles and with this mixture is added the solution The ground ragsserve of being mixed with the chlorid which is in solution and affordingmeans to cause the mass to congeal and hold together. I find that aboutseventy-five per cent. of rags, and

be suificient to form a mass that will possess a durable and .com actcomposition. A larger proportion 0 either the rags or chlorid will tend.to Weaken the resilient Specification of Letters Patent.

' name to this specification in the two subscribing witnesses.

product. After a .pulp is formed by the three elements enumerated,suitable coloring matter is added, according to the use, purpose anddesign desired.

The chlorid of zinc impregnates the particles of rags and paper andcauses the mass to amalgamate. The pulp is now placed into a suitablepress or mold and heated while pressure is applied. The heat andpressure ejects the moisture, at the same time use in connection withknife handles. This is also true with the chlorid. A lar er proportionthan specified app'ears to a cot the congealing of the elements formingthe composition. hat I claim is;

1. A composition (if matter consisting of seventy-five per cent. ofground ra s mixed with twenty five per cent. of chlorid of zinc,

.in solution and. congealed.

A. composition of matter consisting of seventy-five per cent. of groundrags and paper mixed with twenty five per cent. of chlorid of zinc insolution and congealed, the excess of liquid being expelled from themass of material.

In testimony whereof I have signed my presence of HUBERT C. HART.
